Android socket file transfer between two android phones

http://stackoverflow.com –
So im trying to create an android program that transfers a file from one android phone to another. I put the send and receive methods to be called when the send button is clicked, but it doesnt seem to send the file to the destination. (currently testing it with one phone)
Below is the code: any help would be appreciated
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectOutputStre
